Embodiment Construction

[0051]In order to detect, identify and / or locate localized surface and subsurface radioactive geological mineralization using airborne systems, the following must occur: Radiation emitted by an ore body or target (such as a boulder or rock pile) must travel through the ore body and any obstructions (including the ground, vegetation, and air); trapping of radiation by obstructions must be avoided, since each obstruction increases the likelihood that radiation, usually in the form of gamma rays, will be trapped and discontinuous; When it finally reaches an aircraft equipped with at least one radiation detector, it must be fully captured by the detector in order to measure the magnitude of the event that caused the radiation to be emitted. In a preferred embodiment, the radiation detector includes a scintillator that emits light when struck by ionizing radiation (such as gamma radiation) and a photosensor (such as a photomultiplier or photodiode) for sensing When and how much lig...

Abstract

A method for aerially surveying a geographic area for any surface or subterranean radioactive geological deposits using an aircraft having at least one radiation detector element comprises: a) flying the aircraft over the geographic area to be surveyed at a ground speed of between 30 and 60 m / s and at a flight height of between 10 and 20 m above ground level; b) acquiring a series of radiation signal data using at least one radiation detector element while flying the aircraft over at least a portion of the geographic area; and c) storing the series of acquired radiation signal data. A system for conducting the method is also provided.

Description

[0001] Cross References to Existing Applications [0002] This application claims priority under the Paris Convention to US Application No. 61 / 846,543, filed July 15, 2013, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention generally relates to geological survey systems and methods. In particular, the present invention relates to airborne systems and methods for surveying geographic areas and detecting and / or mapping the location of radioactive geological minerals, such as boulders and cairns. In one aspect, the invention has use in detecting uranium deposits. Background technique [0004] Recently, aerial exploration of radioactive minerals has been carried out by flying fixed-wing aircraft equipped with large detectors with a volume of 32 to 48 liters at altitudes of 80 to 150 m and at speeds greater than 220 km / hr over the geographical area to be surveyed. However, data collected in this manner typically doe...
